ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a waterproof sheet for hair washing which prevents wash water from leaking through a gap between a face cover of an automatic hair washer and a face part of a person under hair washing, while hair is washed, and an automatic hair washer using such a waterproof sheet.
BACKGROUND OF THE INVENTION
FIG. 5
is a perspective view schematically illustrating a structure of a face cover part of a prior art automatic hair washer.

and the face of the person and splashing on the face of the person.
However, in the prior art automatic hair washer, since the sizes of the faces vary with persons under hair washing, pressures applied by the face seal to the faces vary with persons, whereby some persons feel something is wrong on the face. Or, when the face of the person under hair washing is quite small, for example, when the person under hair washing is a child, the face seal is not adhered to the face when the face cover is closed. Therefore, a gap is produced between the face part of the person and the face seal, whereby the wash water leaks through the gap.
SUMMARY OF THE INVENTION
The present invention is made to solve the above-mentioned problem and has an object to provide a waterproof sheet for hair washing which can fit to the face of a user according to the size of the face of the user without making the user feel that something is wrong and can prevent the leakage of water, and to provide an automatic hair washer using such a waterproof sheet.
Other objects and advantages of the present invention will become apparent from the detailed description and specific embodiments described are provided only for illustration since various additions and modifications within the spirit and scope of the invention will be apparent to those of skill in the art from the detailed description.
According to a first aspect of the present invention, there is provided a hair washing waterproof sheet used when hair washing is performed with an automatic hair washer, which comprises a cistern capable of accommodating a head part of a person under hair washing, and a face cover which is openably/closably attached to the cistern and has an opening for directing only a face outside, the hair washing waterproof sheet preventing wash water from leaking through a gap between the opening of the face cover and the head part of the person, comprising: an approximately rectangular sheet having an opening in the center; an outer circumference part attached to the automatic hair washer and an inner circumference part in contact with the head part of the person under hair washing, the outer and inner circumference parts being made crinkled by elastically stretchable strings; and coupling means for fixing the inner circumference part to the person under hair washing, the coupling means being provided at opposed positions of a lower part of the inner circumference part. Therefore, when the head is inserted through the opening toward the cistern, the hair washing waterproof sheet can be adjusted according to the size of the face of the person under hair washing so that a gap is not formed between the opening of the face cover and the face part of the person under hair washing, thereby preventing the leakage of the wash water without making the person under hair washing feel something is wrong at the face.
Further, the leakage of water can be prevented more economically with relative to the face cover which is used in the prior art automatic hair washer.
According to a second aspect of the present invention, there is provided an automatic hair washer using the hair washing waterproof sheet according to the first aspect, comprising: a hook for fastening the outer circumference part of the hair washing waterproof sheet, the hook being provided at an edge part of the opening of the face cover. Therefore, it is easy to attach/detach the hair washing waterproof sheet to/from the face cover.
